The potential of agriculture, forestry, and other land uses to sequester carbon offers a powerful tool for controlling the global climate regime, but practices capable of creating “collateral” benefits for landscape conservation have thus far been disregarded. This paper calls for greater integration of scattered trees into agricultural landscapes, hypothesizing that agroforestry practices effectively store carbon and deliver other important ecosystem services as well. Several agroforests from the Upper Lusatia area in Eastern Germany have been selected for analysis. They cover relatively large areas of land (8.2%), even within this intensively used agricultural landscape, and their extent increased from 1964-2008 by 19.4%. Practices of conserving or promoting the six agroforest classes are compared with a catalogue of essential properties for becoming effective “carbon offset projects”. Criteria from mandatory and voluntary carbon markets for carbon sequestration are then applied (additionality, baselines, permanence, and carbon leakage). The study concludes that steps towards realization of “carbon sequestration projects” should include collecting empirical evidence regarding the carbon sequestration potential of temperate agroforestry systems, developing localised demonstration projects, and upscaling these projects to participate in established carbon markets.
Numerous studies underline the importance of immaterial benefits provided by ecosystems and especially by cultural landscapes, which are shaped by intimate human–nature interactions. However, due to methodological challenges, cultural ecosystem services are rarely fully considered in ecosystem services assessments. This study performs a spatially explicit participatory mapping of the complete range of cultural ecosystem services and several disservices perceived by people living in a cultural landscape in Eastern Germany. The results stem from a combination of mapping exercises and structured interviews with 93 persons that were analyzed with statistical and GIS-based techniques. The results show that respondents relate diverse cultural services and multiple local-level sites to their individual well-being. Most importantly, aesthetic values, social relations and educational values were reported. Underlining the holistic nature of cultural ecosystem services, the results reveal bundles of services as well as particular patterns in the perception of these bundles for respondent groups with different socio-demographic backgrounds. Cultural services are not scattered randomly across a landscape, but rather follow specific patterns in terms of the intensity, richness and diversity of their provision. Resulting hotspots and coldspots of ecosystem services provision are related to landscape features and land cover forms. We conclude that, despite remaining methodological challenges, cultural services mapping assessments should be pushed ahead as indispensable elements in the management and protection of cultural landscapes. Spatially explicit information on cultural ecosystem services that incorporates the differentiated perceptions of local populations provides a rich basis for the development of sustainable land management strategies. These could realign the agendas of biodiversity conservation and cultural heritage preservation, thereby fostering multifunctionality.
In diesem Politikpapier definieren die Wissenschaftlerinnen und Wissenschaftler der Nachwuchsgruppe Ökosystemleistungen sieben Leitlinien für die Sicherung und Förderung von Ökosystemleistungen in Kulturlandschaften. Sie zeigen auf, wie diese in dem in Deutschland bestehenden Politikgefüge konkretisiert und implementiert werden können.
